Ecological Networks


We use network analysis and mathematical modeling to understand and quantify the structure, dynamics, and function of biological communities, including their responses to environmental changes such as species extinctions, invasions, climate change, and fisheries. This research program has contributed a more mechanistic understanding of the structure and dynamics of ecological networks, a better integration between theoretical and empirical research in network ecology, and a more predictive theory to evaluate the responses of entire biological communities to environmental change.

Ecological theory of mutualism: Qualitative patterns in two-species population models

Kayla Hale, Fernanda Valdovinos; published in Ecology and Evolution

"Mutualisms are ubiquitous in nature, provide important ecosystem services, and involve many species of interest for conservation. Here, we review historical models of two-species mutualisms from over the last 90 years."
